The electronic map databank 4 includes storage means, such as optical disc (CD or DVD), hard disk, memory card or other similar storage media, for storing correlative data of the electronic map. The electronic map databank 4 includes data fields of geographical information, such as configuration, name of roads, intersections, coordinates and so on. As shown in FIG. 2, the electronic map databank 4 defines correlative information of scenic spots, such as administrative regions, names of the spots, coordinates, whether or not correlative electronic book information exists, and the reference parameters of traveling information of the scenic spots.

The position detection module 6 is mainly a global positioning system (GPS) to receive satellite signals 7 and determine the present position of the vehicle or the user. The position information is then provided to the path selection module 8 and the guidance module 10. The path selection module 8 fetches required scope from the electronic map databank 4 according to the information provided by the position detection module 6. The path selection module 8 determines a start location, a target location and a guidance path according to spot navigation instructions of the scenic spot guidance function initiating module 20 or the input module 2. More specifically, the path selection module 8 receives the present position from the position detection module 6, receives the destination from the scenic spot guidance function initiating module 20, and determines the guidance path to the destination. The guidance module 10 generates a corresponding image to be displayed through the display module 22 after receiving aforesaid information of guidance path, present position and the selected scope of electronic map.

The scenic spot information searching module 12 searches scenic spots within the scope of electronic map selected by the path selection module 8 from the electronic map databank 4 and identifies the scenic spots on the map that include electronic book information.

The traveling information note module 14 provides an information-linking mark and correlative interface to the electronic book information of the scenic spots that are identified of including electronic book information (logically true “1” of judgment). The mark and correlative interface can be an icon, different color or word of “information” or “electronic book” on the scenic spot, and displayed by the display module 22.

The electronic book databank 16 includes storage means, such as optical disc (CD or DVD), hard disk, memory card or other similar storage media, for storing electronic book information of the correlative scenic spots. The electronic book data include traveling information and reference parameters of the scenic spots. As shown in FIG. 3, there are data fields of administrative region, name of spot, coordinate, reference parameter, content, picture and so on.

The scenic spot information obtaining module 18 obtains correspondent electronic book information according to the control of the input module 2 and the comparison of reference parameters of traveling information of scenic spots in the electronic book databank 16.

The display module 22 displays the electronic book, the navigation-linking interface, and the guidance path above.

Therefore, when browsing the map, the user is noted of the scenic spots that have electronic book information. Then, the user can directly choose the “book” mark, text or pull-down menu on or aside the scenic spot to get the electronic book information.

On the other hand, when browsing the electronic book, the user can directly choose the “map” mark or the pull-down menu related to the scenic spot to get the guidance function.

An embodiment of navigation method of the invention is further described below.

Please refer to FIG. 4, which is a flowchart of a multi-function navigation method of the invention in which electronic book information is linkable from the scenic spots in the electronic map.

First, in the map-browsing mode, the navigation system searches the scenic spots in the scope of map relative to the present position according to a scenic spot coordinate table (step 401). Displaying the scenic spots and confirming the scenic spots that include electronic book information according to the data field in the electronic book databank 16 that defines whether the electronic book information exists (step 402).

If a scenic spot includes electronic book information in the electronic book databank 16, then a linking interface and mark to the electronic book information is provided to the scenic spot for noticing the users (step 403). For example, a different display icon or color of the scenic spot is displayed. Then, linking to the electronic book databank 16 when the user operating a pull-down menu, choosing the spot or through other simple interfaces.

When receiving an “information” request of the user, the system searches the corresponding content of the scenic spot according to the relative traveling content parameter in the electronic book databank.

On the contrary, if a scenic spot does not include electronic book information in the electronic book databank 16, then no specific mark, color or linking will be displayed with the scenic spot. So, the user can notice that there is no correlative traveling information.

Moreover, no matter the scenic spot on the map including traveling information or not, the scenic spot icon itself or the neighbor provides a function for the user to directly choose and start the navigation mode.

Please refer to FIG. 5, which is a flowchart of a multi-function navigation method of the invention in which a navigation inquiry is made directly from scenic spots in the electronic book.

First, in the electronic book browsing mode, a navigation-linking mark near the scenic spot is provided for the user to choose and start the navigation function (step 501). When the spot is chosen, the coordinate of the scenic spot is automatically transferred to the path selection module 8. The path selection module 8 judges whether it is a valid coordinate (step 502).

When the coordinate is valid, the guiding path to the scenic spot is found out according to the coordinate (step 503).

When the coordinate is invalid, the process returns to the electronic book browsing mode and displays an error message (step 504).

For further description, please refer to FIG. 2 and FIG. 3, which are data fields defined and established in the electronic map databank 4 and in the electronic book databank 16 respectively.

In the electronic map databank 4, each scenic spot includes data fields of administrative regions, names of spots, coordinates, whether or not correlative electronic book information exists, and reference parameters of traveling information of the scenic spots and so on.

The characteristics are that it contains the field of “whether the correlative electronic book information exists” and “traveling information parameters”. The field of “whether the correlative electronic book information exists” informs the scenic spot information searching module 12 whether or not to find the correlative electronic book information of the scenic spot. The field of traveling information parameters informs the system to get the scenic spot information in the electronic book databank 16. According to the information, the system can quickly find out and display the scenic spot information in the electronic book databank 16.

Moreover, the fields of administrative region and the name of the spot give regional name of county or city where the scenic spot locates and the name of the spot. The field of coordinate provides data for the path guidance and the related position display.

In the electronic book information bank 16, each scenic spot includes data fields of administrative regions, names of the spots, coordinates, traveling information parameters, information content, picture and so on.

The characteristics are that each scenic spot includes data fields of traveling information parameters and the coordinates. The traveling information parameters are similar to that in the electronic map databank 4 for helping the scenic spot information obtaining module 18 to find out the scenic spot information from the electronic book databank 16. The scenic spot information includes telephone number, address, website, business hour, the lowest expense amount, scenery pictures and so on.

The coordinate field provides data for the path selection module 8 to select a guidance path when the user inquiring a guidance to the scenic spot. Then, there is no need for the user to input coordinates manually.

Same, the fields of administrative region and name of spot give regional name of county or city where the scenic spot locates and the name of the spot.

In the embodiment described above, the user chooses guidance function directly from the electronic book. However, it is also applicable using a pull-down menu to add new favorite or to start navigation function. Certainly, the basic manual input of coordinate of the scenic spot to carry on the guidance function is also applicable.

As described above, the invention combines the advantages of full traveling information of electronic books and the convenience of navigation system to let the user notice which scenic spot on the map includes electronic book information. The user can directly choose the scenic spot icon itself, “book” or “information” mark or through a pull-down menu to choose the list and get the electronic book information. On the other hand, when browsing the electronic book, the user may directly start navigation function for a scenic spot through a “map” or “navigation” icon or a pull-down menu.

Therefore, the invention solves the problems of insufficient contents for scenic spots provided by conventional navigation system and the inconvenience of searching books and typing target coordinates for navigation.
